STM32G071CBT6 LQFP48 package. Internal voltage buffer available? Seems not!

​Hello,

Just tried with those 4 lines and it worked fine on my side.

But on QFP64...

  RCC->APBRSTR2 = 0x00000000;

  RCC->APBENR2 |= 0x00000001;

  VREFBUF->CSR |= 0x00000001; // ...00000001 VRS=0, HIZ=0, ENVR=1 => VREF, VREF+Pin = 2.048V

  VREFBUF->CSR &= ~0x00000002;
